Heating / cooling mode
The individual rooms can be configured for pure heating or cooling mode or
for automatic changeover between the two operating modes.
The central apartment unit switches the apartment or individual rooms to
cooling or heating mode as per the settings.
Plants with rooms comprising controllable air conditioners (e.g. air con-
ditioner via Zennio module) can heat or cool rooms independent of
each other.
The rooms are grouped into one apartment. The operating modes and a
holiday/special day program can be set for the apartment. The apartment
operating mode allows for overriding the individual room operating modes.
